摘要：

Electrochemical sensors based on tubular yttria-stabilized zerconia (YSZ) with the spinel-type oxide as a sensing-electrode (SE), which is prepared by sol-gel method, were fabricated and examined for NO2 detection in the temperature range 450 similar to 500 degrees C. The results show that ZnFe2O4, shows extreme sensitivity to NO2. The EMT' varies linearly as a function of the concentration of NO2 (0 similar to 463 ppm) at 500 degrees C.
